• local area-level geographic resolution

When: Taynton Limestone Formation (Great Oolite Group), Middle Bathonian (167.7 - 164.7 Ma)

• The fossiliferous tilestones known as the Stonesfield Slate....are of variable lithology, ranging from calcareous sandstone to siltstone, with impersistent oolitic laminae. They have a characteristic fine, horizontal lamination that allowed the splitting of the 'slates'.

Size class: macrofossils

Preservation: mold/impression, adpression, original carbon

Collection methods: quarrying,
